Hermetic Nano-D Connectors
PacAero’s MIL-DTL-32139 compliant hermetic Nano-D connectors (.025" pitch) are compatible with lightweight materials such as aluminum and titanium, as well as conventional iron/nickel alloys. They are designed for use in military, space, and commercial applications where environmental conditions require an extremely rugged and reliable hermetic seal. The unique controlled CTE characteristics, chemical bonding properties and polycrystalline structure of Kryoflex,® allow PacAero to manufacture this part with a 304L stainless steel insert and gold-plated contacts for excellent electrical performance and environmental characteristics. These hermetic connectors can be produced for both laser-weld and solder-in applications.
PacAero’s hermetic Nano-D connectors are manufactured to exceed the requirements of MIL-DTL-32139.
